97 Toyota Avalon caliper pins location

[YuriyP]

Hi, I got a 97 Avalon and was changing the pads and lubing up the caliper pins the other weekend. Took the sliding pins out and got confused, one of the pins on each wheel has a grove and sliding bushing installed in that grove the other pin does not have any grooves. Here is my question:

• Which pin gets mounted on top and which one goes on the bottom of the caliper? Grooved on top or the bottom?
• In addition, does anyone know if the front is different from the rear are the grooved pins mounted differently on the front (bottom on the front and top for the rear, or bottom on front and rear or top on front and rear)?
• Does anyone know why the pins are different, why one of them is grooved and has a bushing on it, what is the purpose?

Thank you.

For the front the pin with the groove at the end goes on top. The pin has what looks like an anti-slide bushing that would seat in the groove.

The back is a differant design using bolts (pin) treaded at the front, not the back.

On my avalon the rear setup (slider pins) is the same as the front, I looked through Hannes manual and it shows a completely different rear brake assembly than my car maybee I have a split year or something. All I know that the front and back have identical pin setup one with the grove and bushing and the other one isn't. If you can please let me know where does the grove pin in the back go top or bottom. Thank you.

If front is the same as back, would seem logical that the pin with the groove would also go on top.
